Type locality: Mexico.

Our description is drawn largely from specimens which flowered in March 1908 and 

 which were collected by Dr. Rose at Higuerillas, Queretaro, in 1905. Dr. Rose also found 

 this species very abundant in the deserts of Queretaro and living specimens brought back 

 by him have frequently flowered both in New York and Washington. These are identical 

 with plants sent from Berlin, labeled Mammillaria angularis longiseta. The species as here 

 treated is variable and more exhaustive field work might require some modifications in 

 the description. 



The varieties Mammillaria cirrhifera major and M. cirrhifer a fulvispina (Salm-Dyck, 

 Cact. Hort. Dyck. 1844. 11. 1845) ^^e without descriptions. The two varieties M. cirrhi- 

 fera albispina and M. centricirrha macrothele were listed as synonyms of M. subangularis 

 by Walpers (Repert. Bot. 2: 272. 1843). To M. subangularis is also referred M. sub- 

 cirrhifera by Forster (Handb. Cact. 234. 1846).
